CCCC – p. 24 Some recent results Off-shell constraint algebra. Operator results encouraging and fully consistent with effective calculations. [A Perez, D Pranzetti: arXiv:1001.3292] [A Henderson, A Laddha, C Tomlin: arXiv:1204.0211, arXiv:1210.3960] [C Tomlin, M Varadarajan: arXiv:1210.6869] Derivative expansion for integrated holonomies. Work in progress. [with G Paily and J Reyes] Combination of inverse-triad and holonomy corrections. Work in progress. [T Cailleteau]
CCCC – p. 25 Models of quantum space-time (Weak) relation with doubly special relativity. [MB, G Paily: arXiv:1212.4773 ] Holonomy-deformation interpreted as version of κ-Poincaré: −→ Linear N and ⃗w and flat space produce Poincaré if β = 1. −→ For β ≠ 1, dependence on extrinsic curvature takes <strong>the</strong> form of non-linear energy dependence at boundaries. −→ However, this version does not act on standard κ-Minkowski. Background independence and form of quantum space-time remain unclear in loop quantum gravity. Homogeneous models and most extensions do not grasp quantum space-time structure. Not an approximation: just anomalous.
